ZAuth is a Chrome-based tool developed by Hiro, offering users a way to manage their online identity and activity securely. It serves as an alternative to OAuth2, utilizing zkproofs powered by Reclaim Protocol for user authentication on websites.

With ZAuth, users can securely store and use zkproofs offline or in the cloud, granting websites access to these proofs upon user authorization. Additionally, users can generate zkproofs of their identity and activities across various web applications directly within the browser, albeit in an experimental phase.

This tool allows users to conveniently create, read, update, and delete zkproofs, complete with labels and dates for easy management.
